Abstract: 1,216,021. Drying slurries. SOC. GENERALE CERAMIQUE DU BATIMENT. 24 Jan., 1968 [24 Jan., 1967(2); 22 Jan., 1968], No. 3786/68. Heading F4G. [Also in Division C7] Apparatus for extracting and drying solid particles from a liquid slurry in which solid particles are dispersed, e.g. an aqueous slurry, comprises a vessel 1 into which the slurry is fed through a pipe 2 and an electrically conductive rotating drum 3, partly immersed in the slurry, a direct current voltage being applied, between the drum and the vessel, whereby a wet layer P of solid particles is deposited, by electrophoresis, on the surface of drum 3, which may be heated. A satellite roller 5 and a scraper 6 are provided to remove surplus liquid, and a scraper 4 removes the resulting layer P from the drum. Liquid, from which solid particles have been extracted, leaves the vessel 1 through a discharge pipe 8. The drum may be electrically heated to dry the layer P. Alternatively the drum may be provided with a heating jacket, into which a heating medium, such as steam or hot air, is fed through one hollow stub axle, and discharged through a second stub axle. The apparatus may be totally enclosed and subjected to reduced pressure, or the extraction may be carried out in an inert atmosphere. The dried material may be given a granular form, e.g. by providing the roller 5 with indentations, or by providing the drum 5 with a surface which is electrically conductive in a discontinuous pattern, so that solid particles adhere to the drum only in discrete deposits. The dried granules so formed may be removed from drum 5 by a scraper 35, Fig. 7, and conveyed along grooves 36, their passage being assisted by a rotating cylindrical brush (not shown) which bears against the beginning of the grooves and is disposed transversely to the grooves. The drum is rotated at from less than 1 to several revolutions a minute to give sufficient residence time for complete drying. Electrolytes may be added to the liquid to produce a preferred pH of 7 to 8, and the electrolytes can advantageously have a defloculating effect on certain slurries to assist separation; examples of such electrolytes are sodium carbonate and sodium pyrophosphate. Examples are given of suitable voltages, current densities and drying heat for the separation from slurries emulsions or suspensions of clay, sulphur, copper oxychloride, aluminium hydrate and polymers such as polyvinyl chloride.

Title: Improvements in or relating to a gas-liquid contact apparatus
Inventor: HUGGINS CLIFFORD A
IPC: B01D3/16
Filed: 1956-02-10
Abstract: 803,711. Gas-liquid contact apparatus. KOCH ENGINEERING CO., Inc. Feb. 10, 1956, No. 4208/56. Class 55 (2). Gas-liquid, or liquid-liquid, contact apparatus comprises bubble-trays, each tray having openings for the upward passage of one medium, usually gas, which are closed by plate-like members which are free to rise or fall according to the gas-pressure differential on the two sides of the tray, within the limits imposed by locating means on the tray. In Fig. 3, one of the openings 27 is shown surmounted by a dished plate 28 which is confined by a four-legged spider 29, the ends of the legs being split so that they may be spread, as at 30, when they are passed through slots in the tray 16. The cover plates 28 are made of different weights in different zones of the tray 16 so that, at low output with a corresponding low pressure differential, the lighter cover plates 28 only are lifted, and as the output is increased, the heavier covers rise. The spiders may be made with some legs longer than others so that, as the covers rise, they are tilted and thus direct the gas to one side of the cover which assists the flow of liquid across the tray to the downcomer. Trays with one kind of spider may alternate with trays having another sort. An additional thrust on the liquid, to assist it in its movement across the tray, may be imparted by oblique passages 34, Fig. 12, formed by slitting the metal of the tray and upsetting it in opposite directions. The cover plates 28 may present their convex sides to the apertures 27 and may be retained by a two-piece strip which lies over a line of plates 28 and has struck-out parts which engage in notches in the edges of the plates 28. The downcomers may discharge into sealing-troughs which overflow to feed the next lower tray. The resistance to the flow of the liquid across the tray is lessened by forming the tops of the spiders 29 as an inverted unobstructed channel, and the strip system of retaining a line of plates may be modified by providing such a channel throughout the length of the strip.
